Mathml image4
The correct answer is:
Mathml image4
To convert 1.75 into a fraction in lowest terms, you can follow these steps:
Step 1: Identify the whole number part and the decimal part of the number.
In this case, the whole number part is 1 and the decimal part is .75.
Step 2: Since there are two decimal places in .75, we can write it as 75/100 or 3/4.
Step 3: Combine the whole number and the fractional parts.
Since the whole number is 1 and the fractional part is 3/4, we can express 1.75 as a mixed number 1 3/4.
Therefore, the correct answer is Mathml image3, which represents the fraction 7/4 in lowest terms.
To convert the decimal 1.75 into a fraction in its lowest terms, we can follow these steps:
Step 1: Write down the decimal as a fraction by placing it over 1, since it is a whole number.
1.75 = 1.75/1
Step 2: Multiply both the numerator and the denominator by a power of 10 to eliminate the decimal.
1.75/1 = (1.75 × 100)/(1 × 100) = 175/100
Step 3: Simplify the fraction by finding the greatest common divisor (GCD) and dividing both the numerator and denominator by it.
The GCD of 175 and 100 is 25.
175/100 = (175 ÷ 25)/(100 ÷ 25) = 7/4
Hence, the decimal 1.75 as a fraction in its lowest terms is 7/4.
Therefore, the correct answer is Mathml image2.
Question 2 options:
